DETAILED DESCRIPTION

Before any constructions of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other constructions and of being practiced or of being carried out in various ways.

FIGS. 1 and 2 illustrate a length measurement device, more specifically, a tape measure 10. The tape measure 10 includes a coilable measuring tape 14 and a housing assembly 18.

As illustrated in FIG. 1, a variable-length extended segment 22 of the measuring tape 14 is retractable and extendable from the housing assembly 18. A hook member 26 is fixedly coupled to an end portion 30 of the measuring tape 14. The remainder of the measuring tape 14 forms a spool 34 rotatably disposed about an axis 38 of the tape measure 10 (FIG. 2). As shown in FIG. 2, a retraction mechanism 42 is coupled to the spool 34 to provide for powered retraction of the measuring tape 14. The retraction mechanism 42 may include an elongated coiled spring for motive force. A tape lock 46 is provided to selectively engage measuring tape 14, such that the extended segment 22 of the measuring tape 14 remains at a desired length.

Referring to FIG. 1, the housing assembly 18 includes a first side wall 50, a second side wall 54, and a peripheral wall 58 connecting the first side wall 50 and the second side wall 54. The first side wall 50, second side wall 54, and peripheral wall 58 define an internal cavity 62 (FIG. 2) in which the spool 34 and retraction mechanism 42 are housed. Referring to FIG. 1, each of the first side wall 50 and the second side wall 54 has a substantially circular profile 66. In other embodiments, the side walls may be rectangular, polygonal, or any other desired shape. Portions of the housing assembly 18 may be co-molded or separately formed of a resilient material, such as a natural or synthetic rubber. In the illustrated construction, the housing assembly 18 is formed with housing bumpers 70 and a support leg 74 which extends from a lower portion 78 of the peripheral wall 58.

A slot 82 is defined along a forward portion 86 of the peripheral wall 58. The slot 82 is provided to allow for sliding movement of the tape lock 46 relative to housing assembly 18.

Below the slot 82, a tape port 90 is provided in the peripheral wall 58. The tape port 90 has an arcuate shape 94, corresponding to an arcuate cross-sectional profile of the measuring tape 14. The tape port 90 allows for the retraction and extension of the measuring tape 14 to and from the internal cavity 62 (FIG. 2).

As shown in FIGS. 1 and 2, the tape measure includes a finger guard assembly 98. Referring to FIG. 3, the finger guard assembly 98 includes a guard member 102 and a guard support member 106. Exposed portions 110 of the guard member 102 are substantially U-shaped, with a first leg 114 and a second leg 118 extending from the guard support member 106, and a connecting leg 122 extending between the first leg 114 and the second leg 118.

Referring to FIG. 4, a first mounting extension 126 is coupled to the first leg 114, and a second mounting extension 130 is coupled to the second leg 118. Each of the first mounting extension 126 and the second mounting extension 130 includes a mounting boss 134. The guard member 102 may be formed of substantially rigid material such as a metal and is preferably coated or covered with a resilient material such as rubber or plastic. In other constructions, a resilient polymer or other material is used to form the guard member 102.

Referring to FIG. 3, the guard support member 106 is molded over the first mounting extension 126 and the second mounting extension 130 of the guard member 102, such that the exposed portions 110 of the guard member 102 extend from a forward surface 138 of the guard support member 106. The mounting bosses 134 extend outwardly from lateral edges 142 of the guard support member 106. In other constructions, other methods are used to connect the guard support member 106 and the guard member 102 (e.g., thermal bonding, adhesives, fasteners, etc.).

The guard support member 106 further includes a fastener boss 146. Referring to FIG. 2, the fastener boss 146 defines an aperture 150 for receiving a fastener 154 for coupling the guard support member 106 to the housing assembly 18. The boss 134 of each mounting extension 126 and 130 of the guard member 102 are received by corresponding recesses 158

(FIG. 1) formed in the housing assembly 18. The guard support member 106 may be formed of a resilient polymer or rubber material, such that the guard support member 106 provides a degree of impact resistance between the guard member 102 and the housing assembly 18 when the guard member 102 is struck by the hook member 26 or the tape measure 10 is dropped upon the guard member 102. Additionally, the guard support member 106 can rotate relative to the housing assembly 18 about the fastener 154 (FIG. 2) when an impact is received by the guard member 102.

Referring to FIG. 4, the guard member 102, and more specifically the connecting leg 122, is configured to engage the hook member 26 when the measuring tape 14 is fully retracted into the internal cavity 62 (FIG. 1). The guard member 102 also shields the housing assembly 18 from being struck by the hook member 26. In addition, a lower surface 162 of the guard member 102 is substantially aligned with the support leg 74, thereby allowing the tape measure 10 to stand upright on a surface to be measured as shown in FIG. 1.

Thus, the invention provides, among other things, a tape measure and more specifically a tape measure with a guard member.
